Most complete principle of electric gate valve

更新時間:2018.07.20
Electric gate valves are responsive, safe and reliable, and many factories with high control requirements set up compressed air stations for pneumatic control components. Electricity is electricity. A device that controls flow.
First, what is an electric valve? An electric valve simply means to control the valve with an electric actuator, so as to open and close the valve. It can be divided into two parts: the upper part is electric actuator and the lower part is valve.
Ii. Operating principle of electric valve
The electric valve is usually connected by the electric actuator mechanism and valve and becomes an electric valve after installation and debugging. The electric valve USES electric energy as the power to connect the electric actuator to drive the valve, so as to realize the switch and adjustment of the valve. So as to achieve the purpose of switching or regulating the pipeline media. Solenoid valve is a kind of electric valve. The magnetic field generated by the electromagnetic coil is used to pull the valve core, thus changing the opening and breaking of the valve body, the coil is cut off, and the valve core relies on the pressure of the spring to return.
Purpose of electric gate valve: electric valve: it is used to simulate the flow of medium in the pipeline of liquid, gas and wind system. It is controlled by AL. Electric valves can also be used for two - way switch control in large valve and wind systems.
Electric valve: can have AL feedback signal, can be controlled by DO or AO, more common in large pipes and wind valves.
1. Switch form:
The drive of electric valve is to use motor commonly, open or close action completes to need certain time analog quantity, can do adjust.
2. Nature of work:
Electric valves are generally driven by a motor, compared to the voltage impact. Solenoid valve is fast open and fast close, generally used in small flow and small pressure, yo requires the switching frequency of large places electric valve vice versa. The opening degree of the electric valve can be controlled, and the state is on, off, half open and half closed, which can control the flow rate of the pipeline medium, but the electromagnetic valve cannot meet this requirement. Pneumatic gate valves: valves driven by compressed air.
It is not perfect in the current market economy environment that pneumatic valve can meet the procurement requirements only by defining the specifications, categories and working pressure. Because pneumatic valve manufacturers for the product competition, each in the pneumatic valve agreed to design the idea of different innovation, formed their own enterprise standards and product personality. Therefore, it is very necessary to put forward detailed technical requirements in pneumatic valve procurement and reach consensus with manufacturers through coordination.
